USA SAE Thru Hardened Flat Washers with Clear Zinc Cr3 Plating – Strength, Durability & Corrosion Resistance

When strength and corrosion protection are both critical to your fastening application, look no further than the USA-made SAE thru hardened flat washer with clear zinc Cr3 plating. Built for high-performance use in demanding environments, these washers offer the best of both worlds—structural integrity and long-lasting corrosion resistance.

Manufactured from medium carbon steel, these washers undergo a thru hardening heat treatment process to ensure consistent hardness throughout the entire part—not just the surface. This makes them ideal for high-load assemblies where lesser washers may deform or fail under torque.

The clear zinc Cr3 plating adds an attractive, clean finish while offering moderate corrosion resistance. It also meets RoHS compliance, making these washers suitable for environmentally regulated industries like electronics, HVAC, and manufacturing.

Material & Finish:

  • Material: Medium carbon steel (SAE J429 compatible)

  • Finish: Clear Zinc Cr3 plating – bright appearance, moderate corrosion resistance, RoHS compliant

Dimensions & Tolerances:

  • Standard: SAE – smaller outside diameter than USS for precision-fit applications

  • ID/OD: Tight tolerances for secure bolt seating and consistent clamping force

Mechanical Properties:

  • Hardness: Thru hardened for high strength and resistance to crushing or galling

  • Performance: Maintains bolt preload under vibration, pressure, or thermal cycling

Standard Compliance:

  • Conforms to SAE J995 and other SAE washer specifications

  • Made in the USA for premium quality and material traceability

Applications:

  • Automotive assemblies

  • Industrial equipment

  • Light construction

  • Electronics and machinery fastening

For applications where precision, strength, and corrosion protection matter, the USA SAE thru hardened flat washer with zinc Cr3 plating is a smart, reliable choice. Need technical support? Reach out to our team—we’ve got your fastener needs covered.
